I was recently bringing up a custom board with a W6100 chip and it’s funny how closely my experience paralleled this one.
I also had (a different) issue with SPI communication (the W6100 uses a little different protocol).
I still couldn’t get any Ethernet packets to send/receive with a real machine, so I did basically the same debugging step: bought an off the shelf W6100 dev board and planned to use their arduino library to compare against. That’s where I left that project.
